Power Curve measurements from the turbine

Home » Application » Power Curve measurements from the turbine

ZephIR DM provides full rotor wind measurements and turbine motion-compensated true Hub Height measurement.

Understand your turbine’s true potential with a nacelle based power curve measurement.

Remove uncertainties with flow distortion around nacelle anemometry by measuring ahead of the turbine in free wind flow.

Benchmark turbine-to-turbine performance to identify any early underperformance from blade erosion, forestry effects or other mechanical issues.

See the full rotor equivalent wind approaching the turbine to identify wakes, ground-effects and yaw misalignment.

Why? Power Performance Testing (PPT) compares the actual power curve of a wind turbine to the warranted power curve provided by the wind turbine manufacturer.
